Question

1. A stone is projected from level ground with speed
u and at an angle @ with horizontal. Some how
the acceleration due to gravity (Ⓡ) becomes double
(that is 2) immediately after the stone reaches the
maximum height and remains same thereafter
Assuming direction of ncceleration due to gravity
to be vertically downwards. The horizontal range of
the particle is
3 usin 20
sin 20
(a)
(b)
S
28
usin 20
(c) sin 20
S
2g
2
In the question number 1. the angle which the
velocity vector of stone makes with horizontal just
before hitting the ground is given by
(a) tan 6 = 2 tan 8 (b) tan o 2 coto
(c) tano = V2 tane
(**)
(
d
)
(d) tano V2cote​
